The kinetic and potential energy of an object at time t1 are K1 = 31.0 J and U1 = 12.0 J. At time t2 the kinetic energy of the object is K2 = 18.0 J. A. Determine the potential energy and total energy of the object at the time t2 if only conservative forces act on the object. Give your answer in J.B. If the potential energy at t2 is U2 = 21.0 J, determine the amount of work (in J) done on the object by nonconservative forces.
